How do I search for the identity related to an ID address like 69.31.48.15?

Hi scottm6-ga,

You can find information about an IP address (or domain name) using a WHOIS Lookup

Some of the best sites are:
http://www.checkdomain.com/
http://www.networksolutions.com/en_US/whois/index.jhtml
http://www.internic.net/whois.html

From checkdomain, it appears that there are multiple records:
